<p>An object of the present invention is to provide a flexible metallic layered product preferably used for a flexible printed board for flip chip bonding, which is required to have high heat resistance and pressure resistance by improving heat resistance of the flexible metallic layered product, in particular, improving heat resistance of the layer contacting the metallic layer, and a heat resistant adhesive composition. In order to achieve the object, the present invention provides a flexible metallic layered product comprising at least a three-dimensional cross-linking type thermosetting resin layer and a thermoplastic resin layer are layered on a metallic layer in this order. In particular, when a ratio (t1/t2) between the thickness (t1) of the three-dimensional cross-linking type thermosetting resin layer and the thickness (t2) of the total resin layers, which are layered on the metallic layer, is in a range from 7/100 to 85/100, heat resistance of the total resin layers, which are layered on the metallic layer, is more improved.</p> |
